1. Remove jumper wire from terminal
21 and terminal 25 of connector
E-C2 (WP 0012, Figure 143).
2. Connect jumper wire between
terminal 6 and terminal 14 of
connector J-C6
(WP 0012, Figure 141).
3. Disconnect connector J-C8
(WP 0012, Figure 100) from
connector W-C1
(WP 0012, Figure 99).
4. Using digital multimeter

Resistance Greater Than 5.0 Ohms
Replace hitch wiring harness
(WP 0401).

Test Step 17. Verify Malfunction is
Resolved.
1. Ensure all harness connectors are
connected.
2. Turn battery disconnect switch and
ignition switch to ON position
(TM 5-3805-296-10).
3. At MSD, check for active

Active Repeat troubleshooting from
the beginning.
4. Turn ignition switch and battery
disconnect switch to OFF position
(TM 5-3805-296-10).
5. If removed, install splash shield
(Figure 3, Item 4), four bushings
(Figure 3, Item 3), washers
(Figure 3, Item 2), and bolts
(Figure 3, Item 1) on machine.
6. If lowered, install left frame access
plate (WP 0376).
